On “Can someone explain Quantum Cryptography and Quantum Key Distribution in layperson terms?”
Assuming you already have a basic understanding of cryptography this lecture by Chip Elliott should give you the general idea of how everything relates (linked the video to 22:45 because that is where he first starts to mention cryptography in a quantum sense), also touches on some quantum networking.
Hope this helps!
Edit: I found a less technical video on TED here
